here is detail for the end.
For mice or rats. the door is rests on something to keep it open, like a AA battery.
For this application, a nail in the wall would do, or make a hole in the coop wall and insert a short piece of the same pipe as you use for the trap and secure the small piece in place. The door rests on the short piece and the trap lines up with the short piece. When the trap tilts, the door is lifted clear and swings closed.
Excellent detail. Thank you so much. I'm going to make one for my big house and one for the brooder. I also have a rat problem so maybe I'll catch a few of those as well!
Thanks again, I really appreciate it!
